So yesterday i was driving my car. It worked fine in the morning, and on the way to work, but when i got out of work i ran into problems. When i turn the key the car cranks, turns on for two seconds, and then turns back off. Does anybody know what this could be.
(definitely not the battery)

I am not exactly sure, but it is mostly because i am pretty young and i am still getting into the swing of things. Like i stated before, it starts up, idles for a little jitters and then turns off. Me and my father were talking and we were saying how it could possibly be the fuel pump/ fuel filter.

I bought my ob2 reader from harbor freight. It was 129.00 dollars and does everything the 300 dollar snap on one does. Live data reading ect. It tells you what the codes are so no reason to google crap after you read it. Also clears codes of course. Mine has more than paid for itself I use it constantly.
